Depends on why it was an excess deferral if there will be a W-2c.

If it's excess because employer flunked the ADP test - no W-2c.

If it's excess because employee had 2 employers and exceeded the limit - no W-2c.

OP - If the second item is the reason, the excess deferral gets reported as wages in 2022. Some software does this automatically. Don't know about ProSeries.
